java.lang.NoClassDefFoundError: com/google/gwt/junit/client/

[Mal]

This has got me stumped.

I've created a JUnit test class using GWT Designer, but I see this exception when it is run:

java.lang.NoClassDefFoundError: com/google/gwt/junit/client/GWTTestCase

Could you have a quick look at the attached configuration screen and see if there's something wrong?

Regards, Mal.

Sorry, previous image wasn't very readable.

This one's better. Mal.

That is a weird one.

I would try restarting Eclipse, doing a rebuild on your workspace and then try re-creating the launch configuration for your tests.

Still no success.

I have taken it right back to a downloaded GWT application StockWatcher (client-only version) from the Google GWT website
to minimise potential causes.

I'm still seeing java.lang.NoClassDefFoundError: com/google/gwt/junit/client/GWTTestCase

I tried:
(1) restarting Eclipse
(2) doing a rebuild on the workspace (Project > Clean) and then
(3) re-creating the launch configuration for the test

Perhaps these are Google App Engine GWT teething problems.

I'm using
- the Instantiations GWT 7 update site: http://download.instantiations.com/D2GW ... ate/E-3.4/
- GWT SDK 1.6.4
- App Engine SDK 1.2.1
- org.junit_3.8.2.v20080602-1318.junit.jar

Here is an image of the run configuration:

Maybe it doesn't like the junit.jar file.

Does JUnit still work for you guys with the Google App Engine GWT?

I would suggest updating to the latest GWT Designer v7.0 build and see if that helps any.

[Mal]

Thanks Eric. It worked like a charm, first time.

Regards, Mal.

Glad that worked.
